Step 7: Finalise

When you’re done, restart your OS X virtual machine and you should be greeted with a full-res desktop and working audio. You can now continue to insta...

NOTE: This tutorial is now considered outdated and I've published a new instructable with a newer, better and more efficient method to install Mac OS X on your PC, not RUN it! Please refrain from using this tutorial and follow theNew One!

Even if you're a Windows user, you've probably thought about trying the Mac OS X. Maybe you'd like to test OS X before buying a Mac or building a Hackintosh, or maybe you just want to run an app on your Windows machine which is only exclusive for the Mac OS X. Whatever your reason is, you can actually install and run OS X on any Intel-based Windows PC with a program called VirtualBox. Here's how.

Running OS X on your Windows desktop will take a bit of work, but it's pretty easy to do and the final product is quite outstanding. Thanks to Macbreaker and Lifehacker for providing the original instructions! To cut to the chase, here's how to do this.

Step 1: Requirements

Before you start the installation process, you’ll want to gather the following:

- A PC running 64-bit Windows with at least a dual-core processor and 4GB of RAM. Mountain Lion is 64-bit, and thus requires your copy of Windows to be 64-bit. If you’re on a 32-bit version of Windows, you can install Snow Leopard instead (Google it as this instructable is for Mountain Lion not Snow Leopard). Note that your processor also needs to support VT-x. This list should help you find out whether yours does.

- VirtualBox and the VirtualBox Extension Pack: VirtualBox is my favourite virtualisation tool for Windows, and it’s completely free. VirtualBox doesn’t officially support OS X, but it’s actually very easy to get up and running. You should download the main program and the Extension Pack, which will give you support for USB devices.

- A hacked Mountain Lion disc image. Sadly, this won’t work with a vanilla Mountain Lion installer, so you’ll have to find a compatible hacked version. The hacking group Olarila has put a great installation ISO together, and you can find it by searching Google. If that doesn’t fit well with you, you can head over to the Mac App Store and buy a legit copy for yourself, so you can at least pirate with a clear conscience.

- The HackBoot 1 and HackBoot 2 ISO files. Each one has it's own function which you'll know later. However, both will help you boot into the installation.

- Mulitbeast 4, which will help you get audio and other things working correctly after installation. You’ll need to register for a free account over at Tonymacx86.com to download this. Make sure to download MultiBeast 4 — it’s labelled “Lion”, but for our purposes the Lion version works better than the Mountain Lion version.

Yes, there is! I am working on a new tutorial to install Mac OS X on a VM. I am still going through it, it's currently undergoing some tests, but it works as a charm. I'll post that 'ible soon, stay tuned!

This may be a noob question, but why don't you just make the VM and then export it using Virutalbox's Export appliance feature to a file sharing site, or just upload the files that VM is made of. Unless of course this is because you simply don't have a way to upload such large files to the web.

There are several reasons behind not doing this. Firstly, not all people using this method have the same memory (RAM). For example, if you allocated your VM RAM to 4GB and you have a total of 6GB, not all people have 6GB, so they will have to create the VM from scratch. Secondly, with my current internet speed, it would take me a month (maybe more) to upload 13GB (which is the size of the finished VM). Thirdly, this is a tutorial, it is made to make people understand how it works and how to create one, but not just to have it ready.

A bold is structured playing, usually undertaken for amusement and sometimes acclimated as an educational tool. Amateur are audible from work, which is usually agitated out for remuneration, and from art, which is added about an announcement of artful or brainy elements. However, the acumen is not clear-cut, and abounding amateur are as well advised to be plan (such as able players of beholder sports/games) or art (such as jigsaw puzzles or amateur involving an aesthetic blueprint such as Mahjong, solitaire, or some <a href = "http://kuorma-pelit.blogspot.com">kuorma pelit</a>).

No need to post the comment twice my friend, I'll be answering, so please be patient. Anyways, try booting by typing the line below in the chameleon screen

I've really realized that installing OS X is way more better than emulating (VM), so I'll be posting a tutorial on how to install the latest OS X on your PC (not emulate/VM), but I'm just busy these days with my exams, but I'll be posting the 'ible soon. Stay tuned!

Sorry for the double post. I thought maybe I did not do something correctly when it still was not showing up after a few minutes. Tried your suggestion with the same result. The end of the line says debug [796d,bc08,0de1,1e00,01e0,3c00]

I have the same problem as haza4best. The boot process is stuck at the grey apple logo and nothing happens. I did delete the kext file and activated / deactivatet the hackboot2 iso as described. Nevertheless, the resolution (fullscreen widescreen) is okay. This is also my second attempt, but without success.... As soon as I reactivate hackboot2 I can start the system, but without the large resolution.

Same answer. I have just realized now that this tutorial could be considered as an outdated tutorial due to the fact that it is very buggy, so I'm working on a new one, so please be patient. I am sorry if that did not work, but this is a bug as it doesn't occur to all who follow this tutorial, just some of them.
